CPU maxed out when idling under windows with 22.1

CPU maxed out when idling under windows with 22.1

[remi.delmas.3000]

Hi everybody!

I've been using emacs 22.0.50.2 win32 for the last two years without major
problems.

I switched to 22.1 win32 stable this morning, and I have the following problem :
emacs eats 99% CPU when idling, with just two or three files opened in c-mode.

Is there something I can do to solve this problem on my own or does it look like
a bug?

Thanks for your help,

/Rémi

Looks like a bug. Please try to reproduce it in the simplest form
(with -q --no-site-file, as few files as possible, etc.) and send a
bug report with M-x report-emacs-bug.

What binary do you use? I compiled using MinGW and gcc 3.4.5 this
morning and everything works really fine, even on the first approach.

I had the same issue with a prerelease, and it turned out to be the
semantic package. I fixed it with the following line, which basically
turns off the offending process:

; prevent semantic from maxing out the cpu 
(setq semantic-idle-scheduler-idle-time 432000)

Thanks Chris, I'll try that, after some trial and error I located the 
problem in the cedet/ECB extension :)

I'm using the binary release found on the GNU ftp, looking like it was 
compiled with mingw! But it looks like the problem comes from the 
semantic parser
Cheers!

The problem is in semantic-idle.el. You can either set the timeout
very large so semantic's idle processing never kicks in, as suggested
by Chris, or you can get an updated semantic-idle.el from CEDET's CVS
repository. Hopefully CEDET will be released soon - it is almost 2
years since the last pre-release.
